Frontal rain will spread eastwards across the British Isles during Tuesday daytime, beneath an upper ridge. This will be followed by a cold pool aloft overspread relatively warm SSTs, initially across/around Ireland during the afternoon, and then extending eastwards across southern and western Britain on Tuesday night. With reasonably-steep mid-level lapse rates and a few hundred J/kg CAPE, numerous showers will develop over seas and move inland on the west/southwesterly steering flow. A few sporadic lightning strikes will be possible, especially over open water and near adjacent southern or western coasts - particularly south and west Wales, and later in the night Sussex / Kent.
